Low Pressure Casting Machine
Traversing upper machine member for easy die replacement.
In this low pressure casting machine, the 4+4 column vertical press has a system that
allows the automatic traverse of the upper part of the press.
Mold
replacement is then made very easily and time-effective with the use of the
bridge crane, thus avoiding the use of forklifts or other handling equipment
that can interfere with the machine frame.
The electric holding refractory
furnace, with proportional pressurization control, is brought to working
temperature by three heating elements protected by APM tubes made
of sintered steel.
The casting ejection is hydraulically operated and a
rotary arm catches the piece and removes it from the press by swiveling outwards, thus guaranteeing maximum safety for the operator. Thermal control
of the mold is achieved through a system of 8 separate circuits (air, water,
or a mix) and PLC managed.
